This appears to be a contest run by the Milwaukee Journal where the reader had to identify the ballplayer by his eyes. What is odd is it appears this individual decided to go above and beyond and added a bio to each of his ids. There are 12 total photos this entrant identified. Based on Mathewson's bio it appears to be from 1922 as it refers to the benefit game played on his behalf.
Picked it up because it came in a lot with some old Milwaukee Brewer items.
